There is a specific kind of quiet that settles over a house when the power goes out in a storm. The refrigerator stops humming, the air handler goes silent, and within an hour everyone is hunting for flashlights and wondering how long this one will last. For a lot of households, the answer to that last question is what finally tips them toward a standby generator.
Oklahoma gives homeowners plenty of reasons to think about backup power. Spring brings severe thunderstorms and tornadoes, summer brings heat that strains the grid, and winter brings ice storms that pull lines down for days. The December 2023 ice storm and the May 2024 derecho both left parts of the metro dark for the better part of a week. A standby generator turns those stretches from a crisis into an inconvenience.
Standby versus portable
A portable generator is the budget option, and it has its place. You wheel it out, fuel it up, and run an extension cord to a few essentials. The trade-offs are real, though: you have to store fuel, refill it through the outage, and you can only cover one or two things at a time. A standby unit is permanently installed, runs on natural gas or propane, and starts itself automatically when it senses the power drop, covering the whole panel including the air conditioning, the refrigerator, and the well or sump pump.
For a household with central air, medical equipment, or a basement that depends on a sump pump, the standby unit is usually the only option that actually solves the problem. A portable can supplement. It cannot replace.
Sizing it correctly
Sizing is the step people get wrong most often, and it is the one that matters most. A licensed electrician adds up the loads you want covered during an outage and chooses a unit with headroom to spare. A typical Tulsa-area home with central HVAC and a pump lands somewhere between 18 and 26 kilowatts. Larger homes with two HVAC systems can need 30 or more. Undersize the unit to save money and it will trip the first time the air conditioner cycles on under load, which defeats the entire purpose.
Fuel and installation
Most installations here run on natural gas if the home is on a city line, or propane if it is not. Natural gas means effectively unlimited runtime; propane needs a tank but offers more independence. A proper install includes a site survey, a load calculation, a permit, the transfer switch wired into the panel, a fuel-line connection, a pad for the unit, and a final inspection. Plan on a couple of weeks from signing to commissioning, with the on-site work taking one to three days.
One practical note: lead times stretch as storm season ramps up. A transfer switch installed in mild weather is a far easier project than one attempted during an active outage, so the quiet stretches of the year are the right time to act.
Keeping it ready
A standby generator needs an annual service. Oil change, filter, battery check, and a load-bank test. The battery is the most common point of failure, and a generator with a dead battery is just an expensive lawn ornament when the storm finally hits. A simple maintenance plan keeps the unit ready for the day it earns its keep.
The work should always run through a licensed contractor who can handle both the fuel line and the electrical side. In the Tulsa area, Half Moon Plumbing and Electric covers both under Oklahoma Electrical Contractor License #00140295 and Plumbing Contractor License #60313, and the company carries the back-to-back Tulsa World "Best in the World" recognition it earned in 2024 and 2025. Homeowners weighing backup power before the next round of storms can review what proper Tulsa generator installation involves and plan the project for a calm week rather than a chaotic one.
The takeaway
Backup power is one of those purchases that feels optional right up until the moment it is not. The households that install on a plan, size the unit correctly, and keep it serviced are the ones sitting comfortably while the rest of the block waits on the utility crews.
